Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12430, here are decompositions:
- 17 + 12413 = 12430
- 29 + 12401 = 12430
- 53 + 12377 = 12430
- 83 + 12347 = 12430
- 101 + 12329 = 12430
- 107 + 12323 = 12430
- 149 + 12281 = 12430
- 167 + 12263 = 12430
Showing the first eight; more decompositions exist.
